Question

　　Under normal conditions the act of communication requires the presence of at least two persons：one who sends and one who receives the communication．In order to communicate thoughts and feelings，there must be a conversational system of signs or symbols which mean the same to the sender and the receiver．

The means of sending communications are too great in number and various for systematic classification（分类）： therefore，the analysis（分析） must begin with the means of receiving communication．Reception of communication is achieved by our senses．Sight，hearing and touch play the most important roles．Smell and taste play very limited roles．

　　Examples of visual（视觉的） communication are gesture and imitation（模仿）．Although both frequently accompany speech，there are systems that rely only on sight，such as those used by deaf and dumb persons．Another means of communicating visually is by signals of fire，smoke，flags or flashing lights．Feelings may be simply communicated by touch such as by handshaking，although a highly developed system of handshaking has enabled blind，deaf and dumb persons，to communicate intelligently．Whistling to someone，clapping hands in a theatre，and other forms of communication by sound rely upon the ear as a receiver．The most fully developed form of auditory communication is，of course，the spoken language．

The means of communication mentioned so far have two features（特征）： they last only a short time，and the persons involved（牵涉到的） must be relatively close to each other．Therefore，all are limited in time and space．
